详细
论证。软骨发育不全和假性软骨发育不全是遗传性系统性骨骼发育不良,其临床表现有某些相似之处,但病因机制不同。分子遗传学诊断采用多种方法。这些疾病具有共同的表型特征,在对患者进行临床检查、DNA诊断计划以及及时发现神经外科和骨科并发症时,往往会使鉴别诊断复杂化。
目的。该研究旨在确定软骨发育不全和假性软骨发育不全的鉴别诊断标准,并优化其分子遗传诊断策略。
材料与方法。对来自74个无亲属关系家庭的76名年龄在1个月至18岁之间有软骨发育不全和假性软骨发育不全表型体征的儿童进行了全面检查。通过家谱分析、病史资料、临床检查、按照标准方法进行的神经系统检查和放射学检查来明确诊断。通过寻找表皮生长因子受体3(FGFR3)基因的频繁突变、估算位于COMP基因第13外显子中的GAC重复序列的数量,以及对由166个导致遗传性骨骼病变的基因组成的新一代靶向面板进行测序,对疾病诊断进行了分子遗传学确认。
结果。通过对比分析软骨发育不全与假性软骨发育不全患者的表型特征,明确了它们的鉴别诊断标准。在软骨发育不全症中,主要特征是出生时就不成比例的侏儒症、巨颅症和面部畸形,这与假性软骨发育不全症的特征不符。特定的放射学特征对于假性软骨发育不全的鉴别诊断具有重要意义,在转诊患者进行分子遗传学分析时应加以考虑。经证实,绝大多数软骨发育不全患者的FGFR3基因中存在c.1138G>A的重大突变。在27%的假性软骨发育不良患者中,检测到COMP基因中的GAC重复缺失(c.1417_1419del)。基于这些结果,我们得出结论,最好优先分析FGFR3和COMP基因中的这两个突变。如果没有找到突变基因,则应继续进行诊断搜索,使用由166个导致遗传性骨骼病变的基因组成的目标基因面板或完整的外显子组测序。
结论。通过对软骨发育不全和假性软骨发育不全患者样本的临床、放射学和分子遗传学特征进行分析,并结合对文献数据的研究,我们得以明确这些疾病的鉴别诊断标准,并优化其分子遗传学诊断算法。
